AB  - Dust is an environmental, geotechnical, health, and economical hazard. Fugitive 
      dust emanating along transportation systems such as roads, railways, and airports 
      especially can have significant impacts on health, safety, material loss, cost of 
      maintenance, and interfere with the facilities. Quantitative studies on the 
      effectiveness of the proper dust palliatives and their environmental impact have 
      been studied with a number of biological and chemical methods. The objective of 
      this study was to establish a method for using the microbial Induced calcium 
      carbonate precipitation (MICP) approach to reduce the percent of mass loss 
      against erosive force of wind regarding to the concentration and characteristics 
      of aggregate used, climate, and traffic amounts. The results of this study showed 
      that the required precipitation for dust control of sand by 70% is less than 
      15 g CaCO(3)/m(2) between sand grains in bio-treated sand. The wind tunnel test 
      results of this study also indicate that the effectiveness of the bio-treatment 
      method for dust control depends on many variables, such as the percent of 
      precipitated calcium carbonate and tensile strength.
